Loving the game so far. I found a minor sequence break though:
After Sebastian shows you the tree stump in the forest, he's supposed to leave the party before you can exit the forest to the south and it should turn night. I went the long way round to the east though, picking up mints and exiting the forest that way.
The conversation didn't happen then, he stays with me and the sun didn't set. I could take him to Clarissa, where he would disappear during the cutscene and then reappear when i regained control. I didn't push it farther then and reloaded, exiting the forest the correct way.
